What version is your OpenSHH client? If it's >=4.2[*], you can easily
set up a 'master' connection to your mail server. This master
connection is presented as a socket in your ~/.ssh/ directory;
subsequent ssh connections to that same host will check to see if
there's a master socket available. If so, the socket is used -- if
not, a new connection is made.
For example, add the following to your ~/.ssh/config:
Host mailserver
ControlPath ~/.ssh/ctl-%r-%h-%p
ControlMaster auto
Connections to 'mailserver' via ssh will a) check to see if a socket
for that host exists, b) if socket exists, use it, and c) create a
new socket if none is found. This saves on authentication and
encryption overhead on each following connection to the same host.
OpenSSH v4.2 added the modulo-expandables as well as the 'auto'
option for ControlMaster; these additions make this feature much
more usable.
Alternatively, you should be able to use ssh's port forwarding to
accomplish the same goal.
[*] Clients where 3.9 < $VERSION < 4.2 can also do ControlMaster
stuff, but it's more cumbersome.
